这个关键字,很明显有主版本号不一致,改成一致的高版本,jaxb2.3以下的版本需要添加如下四个jar包:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
2.3版本或以上只需要添加jaxws-rt即可,该jar包包含上面4个jar:
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-rt</artifactId>
<version>2.3.0</version>
</dependency>
2019 年浙江大学将要庆祝成立 122 周年。为了准备校庆,校友会收集了所有校友的身份证号。现在需要请你编写程序,根据来参加校庆的所有人士的身份证号,统计来了多少校友。
你猜上述程序输出的是什么? 是 ABC easy as 123 吗? 你执行了输出操作,你才发现输出的是 ABC easy as [C@6e8cf4c6 ,这么一串丑陋的数字是什么鬼? 实际上我们知道字符串与任何数值的相加都会变为字符串,上述事例也不例外, numbers输出其实实际上是调用了Object.toString()方法,让numbers转变为'[c' + '@' + 无符号的十六进制数。
总是觉得自己Java基础还是不行,需要恶补。今天偶然mark了一本《Java解惑》,其中以端程序的方式罗列了95个即常见又不常见的xian(坑)jing(儿),拿来瞻仰一下。
